OEM Carrier Spark Electrode Igniter (48GS400168) for Model PY3PNA036060AA

This is the genuine OEM Carrier spark electrode igniter assembly, part number 48GS400168, factory-specified for the Carrier PY3PNA036060AA packaged unit. The spark electrode igniter is the component responsible for initiating combustion in your gas heating system. When it fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with no heat and a blinking fault code. Replacing this part with the correct OEM assembly restores reliable, repeatable ignition and prevents nuisance lockouts caused by weak or misfired sparks.
